It is +25
Negative fourth root of a number= 1/the fourth root of the number. Fourth root of 625= 5 (5*5*5*5) 1/5
2
Two to the fourth power times 5 to the fourth power equals 10,000
'Squared' & 'Square Root; are the inverse mathemtical functions. 5 (squared) = 25 square root of '25' is 5 Mathematically this would be written as Square ; 5 x 5 = 5^(2) = 25 Square Root ; sqrt(25) = 25^(1/2) = 25^(0.5) = 5 NB THis can be exteneded to 'cubes' and 'cube roots' e.g. 3 x 3 x 3 = 3^(3) = 27 curt(27) = 27^(1/3) = 27^(0.3333.....) - 3 And fourth power and fourth root. e.g. Fourth power ; 2 x 2 x 2 x 2 = 2^(4) = 16 Fourth root = (4th)rt(16) = 16^(1/4) = 16^(0.25) = 2 It can be exteneded to the 'nth power' and the 'nth root'. Where 'n' is any number.
6251/4 = 5
You multiply each of the numbers together and then take the nth principal root, where n is the number of values multiplied together. So Geometric Mean (2, 3, 4, 5) = fourth root of (2*3*4*5) = 120 = 3.31 (approx).
It is: 2/5
5.00
its 5 to the 4th power times 5 to the fourth power and the answer is 390625
A number will have both a positive and negative square root 5 x 5 = 25 and -5 x -5 = 25.
Restricting the discussion to real numbers for now. In this case, the square root is only defined for non-negative numbers; the principal square root of a positive number is the POSITIVE square root. For example, both +5 and -5 are square roots of 25, since both - when squared - give you 25. But the positive square root (+5) is called the principal square root, and if you write the square root symbol, that's the number usually meant.
That refers to the positive root, at least if you take the root of a positive number. For example, 25 has two square roots - two numbers which, when squared, give 25. The positive one (+5) is called the principal square root (or 2nd. root).
